Definitions
- the invention relates to a display device in a motor vehicle, which is arranged behind the vehicle driver and with its display surface facing the interior in the direction of the vehicle driver, the display device being functionally associated with electrical / electronic means for actuating it, according to the preamble of patent claim 1.
- Display devices of this type are already known, for example from DE 4410617 A1.
- a display device which is intended to facilitate parking in reverse by specifying the distance to the rear vehicle or object.
- the optical display unit of the monitoring device is built into the brake light, which acts as the third brake light in the passenger compartment, i.e. is arranged in the rear window area.
- the display device is placed on the brake light fitting or the housing in such a way that it faces the passenger compartment. This enables the display to be viewed from the inside.
- the invention is therefore based on the object of arranging a display device in a motor vehicle for displaying further useful operating data in the overall possible, operating-related field of vision of the vehicle driver.
- a display device in a motor vehicle of the generic type in which a display area is arranged in the interior behind the vehicle driver, but directed towards the same, the object is achieved according to the invention in that the display area is placed in the passenger compartment in such a way that it is above the vehicle driver the interior rear-view mirror is visible, and that the display on the display surface can be generated mirror-inverted.
- the range of vision of the vehicle driver which is usual to the rear in normal driving operation is also used.
- this viewing area is used according to the invention by a display placed there.
- the driver of the vehicle since the driver of the vehicle always looks behind through the mirror, i.e. through the inside mirror, he also has the display placed there in the field of vision when he looks behind. So that he can also read it through the rearview mirror, the display on the display surface can be generated in reverse order.
- an advantageous embodiment of the display device is that the display can be generated mirror-inverted or normally readable depending on the direction of travel or the gear engaged.
- the display on the display surface in question is generated in a mirror-inverted manner via corresponding movement-direction-dependent detectors, so that the display can be read through the rearview mirror, the display being recognized when a reverse gear or a reverse movement is detected is switchable that the display text is now generated normally readable, because the driver usually turns or should turn when moving the vehicle backwards or backwards. He sees the display area directly and the display is due to the directional exposure now readable normally, ie no longer mirrored.
- the direction-dependent changeover i.e. Mirrored or normally readable display generation can be canceled or switched off by a switching element.
- the vehicle driver can determine himself whether he uses the active direction-dependent operating mode of the display device or not. This is particularly advantageous if the driver, in the normal parking situation, habitually reverses without turning only by inspecting all the rear-view mirrors.
- the display device or its electrical or electronic control means is connected to a distance control for displaying the distance to the preceding or following vehicle or stationary vehicle.
- the display device can advantageously be connected to driving operation-related sensors for displaying other driving data.
- This can be data that ensures, for example, that the blind spot is noticed when looking back.
- the switch from mirror-inverted representation to normally readable representation can be realized in a configuration according to the invention with a switching device which is actuated when the reverse gear is engaged.
- the display device in the last advantageous embodiment of the display device according to the invention, its display segments are illuminated and thus also visible in the dark.
- the display can be implemented either as an LED or LCD display.
- the invention is illustrated in the drawing and described in more detail below.
- the figure shows only the orientation of the display orientation to the interior rear-view mirror 10 of the vehicle, which is only shown schematically.
- the respective driver 1 sets the inside mirror 10 anyway for a clear view to the rear.
- the display device 21 can advantageously be placed on the outer surface of the so-called third brake light 20 pointing inward into the passenger compartment his.
- the display can also be placed in the parcel shelf or in the rear window area. In each of these cases, it is ensured that the interior rear view mirror 10, which maps to the rear in a spacious manner, simultaneously leads the display 21 into the field of vision of the vehicle driver.
- the display Since the driver always looks temporarily into the space behind the vehicle during normal driving, as already explained above, in order to be able to see vehicles approaching from a distance, for example, when overtaking, the display is optically coupled to the interior rear-view mirror common viewing position of the driver used for another display. Since the said view to the rear is obligatory anyway, viewing the resulting display does not create any danger of distraction, since it is in the field of vision. Because the display is generated in reverse mirror-readable mode when the vehicle is moving forward, this display can then be read normally again by the driver by looking into the interior rear-view mirror.
- the display in the display area 21 is deliberately generated mirror-inverted, so that the vehicle driver 1 does not turn his head to see the display, but basically does so compulsorily via the interior rear-view mirror 10 and at the same time has the obligatory view to the rear.
- the display generation is dependent on the direction of travel and is switched from mirrored display to normal readable display when driving backwards the vehicle driver actually turns his head backwards when resetting, and the display device can, for example, indicate the distance from the stationary vehicle to which one is approaching by means of distance sensors 26 at the front and 25 at the rear.
- the direction-dependent switching of the display is given by a sensor coupling between the transmission 23 and electronic means 22.
- the display device can be used, for example, to display driving data or data relating to the space to the rear, such as, for example, the distance of the vehicle behind, by the distance sensor 25 at the rear, intention to overtake, relative speed, and the like.
- the display area can thus also be acted upon by the display of distance data from the distance control 27
- the switchover which switches from mirror-inverted to normally readable display, can be switched off by a switching element 24, for example in such a way that the display device also shows mirror-inverted when reversing, so that the said display is normal only in this case due to the interior rear-view mirror Readable
- a switching element 24 for example in such a way that the display device also shows mirror-inverted when reversing, so that the said display is normal only in this case due to the interior rear-view mirror Readable
